This repository provides a series of OPF test cases that were used in the following paper. These test cases are made available here to allow other authors to compare their solution to ours.

V. Roberge, M. Tarbouchi, and F. Okou, “Optimal Power Flow Based on Parallel Metaheuristics on Graphics Processing Units,” Submitted, Jun 2016.


1. The naming of the different test cases is based on the number of buses.
2. The file format is compatible with the MATPOWER Case Format v2 but includes additional structures for transformers and SVARs.
3. The solutions are also provided as a solved MATPOWER case where the optimal settings for the generators, transformers and SVARs are set. To test a solution, one can simply run a power flow analysis in MATPOWER (ex:rumpf('case30_soln.m')).
